We should call update_mmu_cache() even if the PTE was not present before, look at the fault path in mm/memory.c, it does this too. This is where we install hash table entries for newly installed mappings on sparc64 and powerpc, so this update_mmu_cache() call is important even for not-previously-present mappings. - : send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
